Title: Stabilization treatment of residue containing aluminum nitride
Inventor: TAJIMA SEIZO
IPC: B09B3/00
Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To stabilize an aluminum nitride-containing residue in a short time by adding a basic component to the aluminum nitride-containing residue by- produced on the recovery of aluminum. SOLUTION: A residue containing aluminum nitride as a main component is by-produced in a cast purification process aiming at the recovery of aluminum. For example, the residue, by-produced gypsum, and water are charged in a reaction tank 12. Therein, the gypsum containing a basic component is slurried with the water and subsequently added to the residue. Since the aluminum composing the aluminum nitride is an amphoteric element, the aluminum acts as an acidic component on the base. Thereby, the contact of the aluminum with the basic component increases the surface activity of the aluminum and accelerates the hydrolysis of the residue. Thus, the reaction product is produced, and the smell of ammonium is generated. The smell is removed by spraying the dilute aqueous solution of aluminum sulfate on the reaction product from nozzles 14.

Title: Bending die device
Inventor: HOSONO YUKIHITO
IPC: B21D5/04
Filed: 1989-08-05
Abstract: PURPOSE:To automatically perform a pull-out by forming an relief recessed part for intruding a folding side at the time when the side part of a plate stock is subjected to bending to a punch and providing the punch movably in the slanting direction to a holder relatively moving in the approaching and separating directions for a die. CONSTITUTION:When a holder 18 is relatively moved in the direction approaching to a die 14, a punch 22 is moved to the bending position approached to the die 14 and the opposed two side parts at least of a plate stock 2 are subjected to bending in about U shape simultaneously in this state. At this time the bending piece 1 of the plate stock 2 is intruded to the relief recessed part 25 of the punch 22. When the holder 18 is relatively moved in the direction apart from the die 14 after this bending, the punch 22 is moved to the original position to remove the relief recessed part 25 from a bending piece. Consequently the troublesome work of moving this plate stock 2 in the longitudinal direction of the punch 22 becomes unnecessary because of the plate stock 2 being pulled out of the punch 22 after bending. The productivity can thus be improved.
